2011-06-02dahdi: Update the dahdi_ec_chunk interface to support preec streams.Shaun Ruffell
dahdi_ec_chunk is the function that saves the received audio and places a signed linear copy of it in the pre echocanceled buffer on the channel. By splitting the input and output of this function into two parameters, a driver that can provide separate pre and post ec streams can pass them independently to DAHDI, without worrying about DAHDI overwriting a stream that may have already been echocanceled by the hardware. Previously, the dahdi_ec_chunk interface took a received audio buffer and overwrote it after canceling the echo. Now the input and output from the function are broken up in order to support hardware echocans that have a different preechocan stream.

2011-06-02dahdi: Allow dahdi_span_ops.[chan|span]config and startup to block.Shaun Ruffell
This change ensures that the dahdi_span_ops callbacks are not called with any spinlocks held, and that the module is pinned in memory, and also passes the struct file * pointer to the callbacks. Passing the file pointer to the callbacks allows the board drivers to check any flags on the file descriptor used to configure the span/channel. The intent here is to allow dahdi_config to open the /dev/dahdi/ctl file in a non-blocking mode in case there is a lengthy processes that needs to happen as part of configuration.

2011-06-02wct4xxp: Do not set maintstat in t4_clear_maint.Shaun Ruffell
If we always set maintstat to DAHDI_MAINT_NONE, dahdi_base will lose track of what it thinks the current state of the span is. For example, if you run $ dahdi_maint -s 1 --loopback localhost When t4_clear_maint is called, the current maintenance mode state, 'maintstat', is set to DAHDI_MAINT_NONE. So the next time you call: $ dahdi_maint -s 1 --loopback off dahdi-base.c will believe that the user is trying to set the maintenance state from DAHDI_MAINT_NONE to DAHDI_MAINT_NONE and will not actually do anything.

2011-04-15dahdi: Add capability to generate events on buffer underruns and overrunsKinsey Moore
Add BUFFEVENTS and individual buffer event channel flags so that DAHDI can notify userspace processes when it is dropping data. This can be useful when trouble shooting fax problems since DAHDI currently silently discards data becasuse of scheduling latency. With this change, Asterisk could log an event as opposed to just leaving it up to the tone detectors to figure out there was some unexpected phase shift.

This moves the version string into dahdi-version.c that is then linked into dahdi-base.c and dahdi-sysfs.c. This speeds builds on slow computers since dahdi-base.c and dahdi-sysfs.c does not need to be rebuilt if only the version string is changing.

2011-02-20replace old proc interface by modern seq_fileTzafrir Cohen
Switch to using the newer seq_file interface for procfs. Fixes a race when you read the "file" while its size increases (e.g. the span enters an alarm state).

Trival name change to increase readability in the transmitprep and recieveprep functions. Now we clearly define if we are working with an sframe or an eframe.

2011-02-10wct4xxp: Do not lock interrupts while loading the VPM firmware.Shaun Ruffell
Since the oct6100 API consumes less stack there is no longer a danger of overflowing our stack during load. Signed-off-by: Shaun Ruffell <sruffell@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9752 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-02-10wct4xxp: Reduce stack usage in oct612x API.Shaun Ruffell
Reduce the stack usage by replacing the mOCT6100_RETRIEVE_NLP_CONF_DWORD and mOCT6100_SAVE_NLP_CONF_DWORD macros with functions. Some compilers do a better job of optimizing the local variables declared in those macros than others. For example, with gcc 4.3.0, running ]# make stackcheck | grep Oct6100 | head -n 20 | sed -e 's/^0\S* //g' | uniq Before: Oct6100ApiWriteVqeNlpMemory [wct4xxp]: 1112 Oct6100ApiInvalidateChanPlayoutStructs [wct4xxp]:520 Oct6100ApiSetChannelLevelControl [wct4xxp]: 392 Oct6100ApiBridgeEventRemove [wct4xxp]: 344 Oct6100ApiDebugChannelOpen [wct4xxp]: 312 Oct6100ApiWriteVqeAfMemory [wct4xxp]: 296 Oct6100ApiSetChannelTailConfiguration [wct4xxp]:264 Oct6100ApiRandomMemoryWrite [wct4xxp]: 248 Oct6100ApiTransferToneEvents [wct4xxp]: 248 Oct6100ApiModifyChannelStructs [wct4xxp]: 232 After: Oct6100ApiBridgeEventRemove [wct4xxp]: 344 Oct6100ApiDebugChannelOpen [wct4xxp]: 312 Oct6100ApiRandomMemoryWrite [wct4xxp]: 248 Oct6100ApiTransferToneEvents [wct4xxp]: 248 Oct6100ApiInvalidateChanPlayoutStructs [wct4xxp]:248 Oct6100ApiModifyChannelStructs [wct4xxp]: 232 Oct6100ApiBridgeRemoveParticipantFromChannel [wct4xxp]:216 Oct6100ApiWriteVqeNlpMemory [wct4xxp]: 200 Oct6100ApiInitChannels [wct4xxp]: 168 Oct6100ApiProgramNLP [wct4xxp]: 168 Signed-off-by: Shaun Ruffell <sruffell@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9751 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2011-02-10wct4xxp: Reduce the memory footprint of the hardware echocanceler.Shaun Ruffell
This saves ~300K of kernel memory for each quad or dual span VPM. Due to the fact that this change disables caching of the NLP words (among other things), the time to disable the echocans appears to have increased by ~1ms.
